SOUTH BEND -- Police believe they've cleared up seven robberies with the arrests of an alleged modern-day Bonnie and Clyde. The boyfriend has a lengthy criminal history and has been accused in three recent bank robberies, while the girlfriend recently made headlines by using a screwdriver to reportedly rob the same Speedway twice this week. Capt. Phil Trent, a South Bend police spokesman, called the man, Andrew D. Patterson Jr., "a one-man crime wave." Trent wrote in news releases that his department cleared up four bank robberies and one gas station robbery with the arrest of Patterson, 31, of Mishawaka. His girlfriend became involved this week, according to Trent, who said Patterson drove her to rob a gas station twice, using the screwdriver as the weapon. She is Kayla A. Dill, 19, of Osceola. "We're getting rocked by bank robberies here (in South Bend)," Trent said, acknowledging that the city has more unsolved bank crimes. "But this guy is significant." Patterson has a criminal history that starts with him pleading guilty to two bank robberies that took place in July 2001. "He got locked up on bank robbery charges before and started doing them again," Trent said. "There's absolutely no reason to believe that he was going to stop for any reasons." Trent wrote that the cases were cleared "as a result of excellent investigative work by uniform officers, forensic laboratory personnel and detectives." He said an officer recognized Patterson as a possible suspect from "a blurry bank surveillance camera." Patterson's fingerprint also was found on a piece of paper found at one of the robberies, according to Trent. Dill was arrested on suspicion of two separate robberies of the Speedway gas station at 1110 E. Ireland Road on New Year's Day and Wednesday. Patterson originally was arrested on outstanding warrants for motor vehicle theft and failure to appear. As of Friday afternoon, the St. Joseph County prosecutor's office was reviewing reports on the robberies. Trent said that since his arrest, Patterson has admitted to robbing the 1st Source Bank at 4105 Lincoln Way W. on Dec. 10; robbery of the Speedway gas station at 2150 E. South Bend Ave. on Sunday; stealing three cars to be used in the robberies; and driving his girlfriend to commit the other two robberies. Police said Thursday that Patterson was wanted in connection with the Dec. 18 robbery of the MFB bank on Ireland Road, the Christmas Eve robbery of the Portage Avenue Notre Dame Federal Credit Union, and the Wednesday robbery of the Mishawaka Avenue MFB.
